Series 40 Theme v2.0 is meant for 3d Edition phonesSeries 40 Theme v3.0 is for 5th and 6th Edition phones

Themes saved with the 2.0 option are installable on 3d, 5th and 6th Edition phones.Themes saved with the 3.0 option are only installable on 5th and 6th Edition phones.

If you put a 2.0 theme on a 5th or 6th Edition phone, it will work but some of the elements (the ones that are only supported by 5th and 6th Edition phones) will remain in default state, no matter if you skinned them in Carbide UI or not.

There are six 240x320 6th Edition phones till now and their number will soon increase, so it might be interesting to know about the differences between themes put on 5th, resp. 6th Edition phones.

(The height difference between the 5th and 6th Edition screens is due to the 6th Edition emulator I took the screenshots from. It's 320x480 instead of 240x320.)

Here we go:

Different default iconsBy default, 6th Edition phones show the new OVI icons.

Black statusbar gradientOn 6th edition phones, the statusbar icons are white instead of colourful. Additionally, there's now a permanent black gradient in the statusbar of all screens (except on the Idle Screen).

ScrollbarWhen you skin the scrollbar in Carbide UI, the changes won't show up on 5th Edition phones. But they do on 6th Edition ones:

Dim ColourWhen a popup appears, the submenue background is automatically dimmed black on 5th Edition phones. For 6th edition phones, you can now assign the dimming colour (example: pink) by selecting General > Dimming > Background Color in Carbide UI. When you don't skin it, it will be black.

Skinning of List Highlight for unavailable items now supportedThere are two separate list highlights, one for available and one for unavailable list items. Both can be skinned in Carbide UI*, but only the first one will appear on most 5th Edition phones while the latter one remains dark grey with a dark blue text. On 6th Edition phones, this bug has been fixed.

Separate Tab Background not supported anymoreIn Carbide UI, you can apply a separate background for the Tab View but you will only see it on 5th Edition phones. 6th Edition phones automatically use the Background Main image instead. However, the Tab Highlight is still supported.
